Conditions

Interventions

BEHAVIORAL

Video Task

Subjects are asked to watch a series of six two-minute video clips. The video clips are designed to induce sad or happy emotions or no emotion (neutral) and are taken from movies, documentaries, or instructional videos. There are two videos for each emotion condition. Videos and fixation cross screens are viewed on a laptop computer. In between video clips, patients are asked to quietly look at a fixation cross for one minute, describe their emotional reaction to the video for up to one minute, then again attend to a fixation cross for one minute. A video recording of the frontal view of the participant's face will be made during task performance.

OTHER

Imaginal Task

Subjects are asked to think about happy or sad memories for 2 minutes. Subjects are asked to imagine performing neutral tasks, such as buying groceries. Subjects are then asked to think about a memory that makes them feel angry. A video recording of the frontal view of the participant's face will be made during task performance.
